In the 2005 show season the American Dahlia Society gave this longtime favorite more awards than any other giant formal decorative Dahlia. We just can't resist this stunner with monster 10–12in flowers, which are a clear, penetrating pale yellow. It's one of the easiest Dahlias to grow and the ideal choice for your first giant Dahlia. Decorative form.

We can't think of a genus that offers more variety of color and form than Dahlia. These hybrids of species native from Mexico to Colombia hold their display in reserve for mid- to late summer and early fall, when most gardens and most vases are looking a little tired. Planted in 3s and 6s, they serve to fill holes that develop in the perennial border and make excellent potted plants (1 tuber in a 12in pot).

Dahlias prefer full sun, though partial shade is acceptable. They like rich soil and even moisture, which means regular watering in areas with hot, dry summers. Dahlias are perennial in Zones 8-10. Where they are not hardy, Dahlias are easily overwintered indoors (details in the Cultural Instructions booklet that will accompany your order, or by clicking on "Growing Guide & Tips").
